William F. Morgan

William F. Morgan was an American engineer and inventor best known for developing the first practical electroencephalography (EEG) device in the 1930s. EEG is a technique for recording electrical activity of the brain, which has become essential in neuroscience and medicine for diagnosing conditions like epilepsy. Morgan’s work provided a reliable way to measure brain waves non-invasively, greatly advancing neurological research and clinical practice. His contributions laid the groundwork for modern brain wave analysis and the use of EEG in medical diagnostics, profoundly impacting how we understand and monitor brain activity.
